Effects of school-based physical activity on mathematics performance in children: a systematic review
2019
AbstractBackgroundThe benefits of physical activity (PA) on children’s health and wellbeing are well established. However, the benefits of PA on academic performance and particularly on mathematics performance warrant systematic analysis. Mathematics is one of the core subjects in school education globally.MethodsWe systematically searched, analysed and synthesized the literature on the effects of school-based PA interventions on mathematics performance in children aged 4–16. A total of 29 studies consisting of randomised trials and other interventions with control groups were identified through a systematic search, and 11 of them provided sufficient data and appropriate design for a meta-a…
Chemical Transfers Occurring Through
2019
Chardonnay wine malolactic fermentations were carried out to evaluate the chemical transfers occurring at the wood/wine interface in the presence of two different bacterial lifestyles. To do this, Oenococcus oeni was inoculated into must and wine in its planktonic and biofilm lifestyles, whether adhering or not to oak chips, leading to three distinct enological conditions: (i) post-alcoholic fermentation inoculation in wine in the absence of oak chips, (ii) post-alcoholic fermentation inoculation in wine in the presence of oak chips, and (iii) co-inoculation of both Saccharomyces cerevisiae and O. oeni directly in Chardonnay musts in the presence of oak chips. Classical microbiological and …
Organic food consumption: The relevance of the health attribute
2020
During the last decades, organic food products have become the main sustainable alternative to conventional food consumption. Among the several organic food attributes that consumers recognize in organic food, healthiness has been reported as the primary motivation to buy products certified as organic. The objective of the current study is to assess the relative weight of the health attribute among other recognized organic food attributes. To achieve this aim, a multiple price list (MPL) methodology is adopted to elicit consumers&rsquo
From beverage to companion food: Experts' principles for pairing wines and beers with food
2016
Projet "Associations entre bières et mets : de la perception au jugement des consommateurs en situation réelle de consommation".; Pairing beverages and dishes is part of culinary tradition. The objective is to identify the principles used by experts for pairing. Ten sommeliers and ten beer experts were presented with the description of a drink, either beer or wine. They were asked to suggest dishes to match the drink and explaining their choices. They performed the task with two beers and two wines. Both perceptual and conceptual principles are reported, the former being the most often used. Overall, 10 perceptual principles were identified. They intend to either reinforce the quality of th…
Energetic demands and nutritional strategies of elite cross-country skiers during Tour de Ski : A narrative review
2021
The Tour de Ski (TDS: 6–9 sprint and distance races across 9–11 days) represents the most intense competition series of the cross-country (XC) ski season and is characterized by accumulated stress from consecutive days of high-intensity (~ 85%–160% VO2max) racing, travel, cold temperatures and low to moderate altitude (500–1500 m above sea level). Here, nutritional strategies play a key supportive role for optimized health, recovery and performance. This narrative review aims to provide an evidence-based discussion on the energetic demands of the TDS and recommendations for nutritional strategies to optimize health and performance of XC skiers during and following the TDS. We highlight seve…
Evidence for Positive Selection in the Capsid Protein-Coding Region of the Foot-and-Mouth Disease Virus (FMDV) Subjected to Experimental Passage Regi…
2001
We present sequence data from two genomic regions of foot-and-mouth disease virus (FMDV) subjected to several experimental passage regimens. Maximum-likelihood estimates of the nonsynonymous-to-synonymous rate ratio parameter (dN/dS) suggested the action of positive selection on some antigenic sites of the FMDV capsid during some experimental passages. These antigenic sites showed an accumulation of convergent amino acid replacements during massive serial cytolytic passages and also in persistent infections of FMDV in cell culture. This accumulation was most significant at the antigenic site A (the G-H loop of capsid VP1), which includes an Arg-Gly-Asp (RGD) cellular recognition motif. Our …
Children’s Fruit and Vegetable Preferences Are Associated with Their Mothers’ and Fathers’ Preferences
2021
Children’s preference for fruit and vegetables must emerge during childhood. At children’s homes, mothers and fathers influence children’s developing food preferences with their own preferences and actions. The purpose of the study was to reveal the association parents have with their children’s fruit and vegetable preferences. The study was conducted in a sample of Finnish mothers and fathers of 3–5-year-old children. The participants were recruited, and questionnaires distributed through early childhood education and care centers in 2014 and 2015. The results showed considerable variance in the children’s preferences, and were more similar with their father’s, than their mother’s preferen…
Identification of various retention/release behaviours of odorant molecules in dairy and pectin gels: the role of structural features
2014
Reducing the fat content in food requires a reformulation by adding thickeners that may cause a different perception of aroma. Maintaining an adequate level of acceptability of these reformulated products for consumers requires a better understanding of the mechanisms that control the retention/release balance of odorant molecules in food matrices. [1]. Although pectins are commonly employed as thickeners [2], their effect on the retention of odorant molecules in nonhomogeneous products [3, 4] has been examined more frequently than their effect on the retention of odorant molecules in simple model gels [5]. The purpose of this study was to explore and compare the effects of pectin in differ…
Testing for Lynch Syndrome in Endometrial Carcinoma: From Universal to Age-Selective MLH1 Methylation Analysis
2022
Simple Summary International guidelines recommend universal screening of endometrial carcinoma patients for Lynch syndrome, a hereditary cancer predisposition syndrome. Screening is based on mismatch repair protein immunohistochemistry and reflex MLH1 methylation analysis to exclude the likely sporadic cases of MMR deficiency. As sporadic MLH1 protein loss is common in endometrial carcinoma, the ability to target methylation testing would save efforts and costs. We discovered that limiting methylation testing to patients under 65 years would have significantly reduced the testing effort while maintaining a low false negative rate for MLH1-LS detection (0% and 3% in our clinic and registry-b…
Patērētāju tiesības un personalizētās reklāmas: patērētāju ievainojamības izmantošanas risks (Kopsavilkums)
2020
Have you ever received a frighteningly personalised advertisement with a specific product at the moment when you are thinking about buying that product? Digital technologies have huge positive potential, but their uncontrolled use poses many risks. However, the notion that the current direction of technological development is unavoidable and that the problematic aspects of technology simply need to be tolerated poses a much greater threat to the future. Therefore, this paper discusses one of the risks – personalised advertising that seeks to exploit consumer vulnerabilities. Thereby, the aim of the article is to analyse legal problems of targeted and personalised advertising that seeks to e…
